The wart blocks have been updated with slight touches to the normals and details blending. The blocks in question are the nether wart block and the warped wart block.
Here are (a lot of) screenshots showcasing those changes. Nothing dramatic or major but an overall improvement and better consistency with regards to depth and other small features blending.
